1.за первый час было расчищено от снега пять 17-х всей дороги,а за второй час --девять 17-х всей дороги.какая часть дороги расчищена от снега за эти два часа7На какую часть дороги было расчищено в первый час ,чем во второй? 2.На платье для первой куклы было израсходованно шесть 25-х м. ткани ,а на платье для втрой куклы--девять 25 м. ткани.Сколько ткани было израсходованно на оба платья?на сколько больше ткани было израсходованно на платье второй куклы ,чем на платье перврй куклы? ПОМОГИТЕ РЕШИТЬ))

Answer 1

№1.1)5/17+9/17=14/17(части) - за 2 часа расчіщищено

2)9/17-5/17=4/17(части) - на столько расчищено меньше в 1 час чем  во 2

Ответ: 14/17 расчищено, 4/17-на столько расчищено меньше в 1 час чем  во 2.

№2.1)6/25+9/25=15/25=3/5=0.6(м) - на 2 куклы

2)9/25-6/25=3/25=0.12(м)

Ответ: 0.6м на 2 куклы, 0.12м больше на 2 куклу.

Answer 2

Question 1:

To find the fraction of the road cleared of snow in the first two hours and the difference in the amount of road cleared in the first and second hours, we need to calculate the fractions for each hour.

In the first hour, 5/17 of the entire road was cleared of snow. In the second hour, 9/17 of the entire road was cleared of snow.

To find the fraction of the road cleared in the first two hours, we add the fractions for each hour: 5/17 + 9/17 = 14/17.

Therefore, 14/17 of the road was cleared of snow in the first two hours.

To find the difference in the amount of road cleared in the first and second hours, we subtract the fractions: 9/17 - 5/17 = 4/17.

Therefore, the amount of road cleared in the first hour was 4/17 more than in the second hour.

Question 2:

To find the total amount of fabric used for both dresses and the difference in the amount of fabric used for the second doll's dress compared to the first doll's dress, we need to calculate the amounts for each dress.

For the first doll's dress, 6/25 meters of fabric were used. For the second doll's dress, 9/25 meters of fabric were used.

To find the total amount of fabric used for both dresses, we add the amounts for each dress: 6/25 + 9/25 = 15/25.

Therefore, a total of 15/25 meters of fabric were used for both dresses.

To find the difference in the amount of fabric used for the second doll's dress compared to the first doll's dress, we subtract the amounts: 9/25 - 6/25 = 3/25.

Therefore, the amount of fabric used for the second doll's dress was 3/25 meters more than the amount used for the first doll's dress.
